Specification of Letters Patent.

To all whom it may concern:

Be it known that I, CARL A. MATSON, a subject of the King of Sweden, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful- Improvements in Heel-Burnishing Machines, of which the following is a specification.

This invention relates to burnishing machines and particularly to machines for burnishing the soles and heels of boots and shoes.

The object of the invention is to provide a machine which will melt wax and deposit the same upon the periphery of a burnishing wheel in a predetermined quantity and is also adapted to remove more or less of said wax from said wheel and return the same to the wax pot where it is remelted and reapplied to said burnishing wheel.

The object is further to provide amachine in which the working parts are carefully covered to prevent the wax from being thrown about, yet said parts are all readily accessible to the operator, especially the burnishing wheel which may be removed and replaced at will.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings: Figure 1 is a front elevation of a portion of a burnishing machine embodying my invention. Fig. 2 is an end elevation of the same as viewed from the left, Fig. 1. Fig. 3 is a section, partly in elevation, taken on line 33 of Fig. 1 and viewed in the direction of the arrows. Fig. 4 is a section, partly in elevation, taken on line 44 of Fig. 2.

Like numerals refer to like parts through out the several views of the drawings.

In the drawings, 7 is a rotary burnishing wheel having a convex yielding periphery 8, consisting of a hollow cylindrical core 9 from eachside of which extend reduced cylindrical portions 10 and 11, A rim 12 of yielding material, preferably felt, is placed about the cylindrical core 9'and firmly 'held in place by a canvas covering 13, said covering being clamped between the sides of the core 9 and washers 14, 14 by spanner nuts 15, 15 having screw-threaded engagement with the reduced cylindrical portions 10 and 11 of said core. Interposed between the relation to the burnishing wheel 7 canvas covering 13 and the felt rim 12 is .a sheet of Water-proof material 13' to pre vent the melted wax from passing through the canvas covering and into the felt. A hub 16 projects from the side of the cylindrical portion 11 and is secured upon the end of a shaft 17 journaled to rotate in bearings 18 in the frame 19 of said machine, said shaft also having a pulley 20 fast thereon through which a rotary motion is imparted to the burnishing wheel 7-.

In the burnishing of soles or heels of boots and shoes it is essential that a certain amount of wax be applied to the tool before a smooth'polished surface can be pro duced and for this purpose a wax 'pot 21 is provided, it being located adjacent to the lowermost part of the periphery of said wheel and preferably embodying in its construe: tion a wax reservoir 22 into which said burnishing wheel 7 projects, a wax supply chamber 23 and a float chamber 24 intermediate said wax supply chamber and said reservoir. A float 25- in said float chamber 24 controls the flow of wax from the supply chamber 23 through a port 26 by means of a valve 27 having -a seat '28 in the bottom 29 of said float chamber. The valve 27 has a screw-threaded valve stem 30 engaging a plate 31 fastened to said float and by the adjustment of said stem with relation to said float more or less wax is allowed to flow into said -chamber. An equal level of the wax is maintained in the fioat'chamber 24 and reservoir 22 by means of a port 32 connecting said chambers.

The wax pot 21 is supported in its, pio'per y a shield 33 formed in two parts, a lower part 34 which contains said wax pot and an upper part 35 pivoted at 36 to said lower part, said lower and said upper parts inclosing the greater portion of the periphery of said burnishing wheel. Said upper and lower parts are locked against relative movement by a lever 46 :pivote'd upon a stud -17 securedv in the upper part '35 and engaging a log 48 on the lower part 34 through a screw 49 having screw-threaded engagement with said lever, whereby more or less pressure may be brought to bear upon the abutting surfaces 50 and 51 of the upper and lower parts of said shield, respectively. A lug 37 projects downwardly from the lower part of said shield and is clamped to a lug 38 on. the frame 19 by. a screw 40. Vertical adjustability of said shield relatively to the axis of said burnishing wheel is permitted by a slot 41in said lug 37, through which the screw 40 projects, and a tongue 42 on said lug 37 engaging acorresponding groove 43 in the lug 38.

Engaging the periphery of the wheel 7, intermediate the wax reservoir 22 and a gap 44 in the'shield 33 through which the shoe is presented, is a roll 45 having a concave face to which the yielding periphery of said burnishing roll conforms, said roll being rotatively mounted upon a shaft 52 guided in slots 53, 53 in the plates 54, 54 secured to side walls of the shield 33, said shaft 52 being prevented from rotating by the flattened faces 58, 58 at the ends of said shaft engaging the sides of said slots 53, 53. Springs 55, 55"seated upon the shaft 52 are engaged by screws 57, 57 having screwthreaded engagement with the casing 56 inclosing the roll 45, said springs 55 and screws 57 forming a means whereby an adjustable yielding pressure may be applied to said roll 45. I

The wax in all the different compartments of the wax pot 21 is retained in a liquid state by heat applied to the walls of a recess 59 through the instrumentality of a gas burner 60" supported upon the frame 19 and adjacent to said recess. Said recess 59 is formed in the bottom of the wax pot '21, the walls of said recess forming a portion of the walls of each of the wax chambers 23 and 24 and wax reservoir 22. Another gas burner 61 is secured to the shield 33 and projects through an opening 62 in said shield and into the interior of the roll 45, whereby said roll is heated to melt and remove more or less of the wax deposited u on the periphery of the burnishing wheel Both of said burners 60 and 61 are connected to a main gas supply by flexible tubes, thus permitting movement of said shield without disconnecting said burners.

roll 45 being heated and said roll beingun-.

der compression against the face of said burnishing wheel, more or less of the wax previously deposited upon .the periphery of.

said wheel is removed and flows back and into the reservoir 22 where it is remelted and again applied, thus allowing just the required amount of wax to pass around on said wheel to said shoe. The wax is placed in the supply chamber 23 where it is melted by the gas burner 60'adjacent to the under side of said wax pot, said wax passing from said supply chamber through the port 26 and into the float chamber 24 from which it the port 32 and .is retained at the desired ing of said float, whereby the valve 27 is moved toward and away from the valveseat 28. When it is desired to remove the burnishing wheel from the shaft 9, the adjusting screw 49 in the lever 46 is released and said lever is rocked upon its pivot to clear-the lug 48, thereby allowing the upper part 35 of the shield 33 to be swung back upon its pivot 36, carrying with it the roll 45. The screw 40 is then released and the lower part 34 of said shield is moved downwardly until the end of the slot 41 engages said screw and the edge 63 of said shield is clear of the periphery of said roll, thereby making a clear passage for the wheel to be slipped from the end of the shaft 17.

The object of introducing the water-proof sheet material 13 between the canvas covering 13' and the felt 12 'is to prevent the' level in said reservoir by the rising and fallthe felt becoming hard and stiff, so as to very much impair its efficiency as a burnishing roll.- By introducing the water-proof material between the outside cover of canvas and the felt this difficulty is'entirely avoided.

Having thus described my invention, what I claim and desire by Letters Patent to secure is: v i

1. In a burnishing machine for boots and shoes, a wax potembodying in its construction a wax reservoir also having a wax sup-.

ply chamber and a float chamber, said float chamber being intermediate said reservoir and supply chamber and connecting said chambers, said wax pot having a recess formed in the bottom thereof, the walls of said recess forming a portion of the walls of each of said wax chambers and said reservoir; in combination with a single means to heat the walls of said recess whereby the wax in said chambers and said reservoir is retained in a liquid state, a float within said float chamber adapted to control the flow of wax therethrough, a burnishing wheel, and

means to remove the superfluous wax from the periphery of said burnishing wheel.

2. A burnishing machine for boots and shoes. having, in combination, a burnishing wheel, a shield inclosing a portion of the periphery of said wheel and formed in two parts, the lower of said parts adapted to 'be moved toward and from the axls of said burnishing wheel, and the upper of said parts movable relative to said lower part, whereby said parts may be separated to alringers low the removal of said burnishing Wheel,

a Wax pot supported by the lower part of said shield, and an idler r011 yieldingly mounted to rotate in the upper part of said shield and engaging the periphery of said burnishing wheel.

3. A burnishing machine for boots and shoes having, in combination, a burnishing wheel, a shield inclosing a portion of the periphery thereof and formed in two parts, one of said parts adapted to be moved toward and from the axis of saidwheel, the
